I have an 09' Limited with Weathertech Digital fit mats. I know the mats hold in and pool liquid so they don't get on the mats. I've had a lot of condensation lately on all windows. I removed the Weathertech mat to get the small amount of water that was on it and noticed the driver side carpet was wet (all of the other spots are fine). Firewall isn't wet - put my fingers under the door trim and there is some wetness (don't know if that's the source but just checked). Called service and they advised me to take the mat out and let it dry. Said it could be that the snow/water on the carpet could be from leaking/coming down from where the mat connects to the car. Heard the AC drain may be the culprit but any assistance may help.
